This one I marked in yellow?

Fuse F1 is on that tcon (2nd pic). You need a multimeter to see if it is good or bad.

Hope this works!

Re: Dell WFP 2007 No image

Hurrah! that's the one but the picture is no good - did you look at it since you posted it?
I can barely make out the main chip let alone a fuse that will be a few millimeters across.
Take pic in 3 sections overlapping - must be well lit and in focus so it can be enlarged.

This one?
Regarding the YT video, that guy told me to contact you guys

Re: Dell WFP 2007 No image

We cant see the board but yes you need to go in further.
Here is an interesting video - set similar to yours - will help with the part names

He doesnt go in far enough but there is a board under the metal plate
in the following picture taken from the video. This is the other end of the cable
shown in the red box in retiredcaps picture.

Re: Dell WFP 2007 No image

So you are saying that It should be more boards near the panel? Should I keep dissembling the case?

So far I have 4 boards, but as I'm not an expert, I don't how to named them. Please point me to the right one, and I'll take more pictures in detail.

Thanks!

Re: Dell WFP 2007 No image

bottom pic 4645 its the orange component om the bottom right of the multi coloured cable

That is one fuse - Think retiredcaps was meaning one at the other end of the lvds cable ie probably attached to the panel and probably behind a metal frame.


@ noisepc
Unfortunately your pictures are too blurry for us to see the details. Did you look at them on screen to see what they look like?

Having said that in the pic attached I think the white item in the yellow box is a fuse - what I am saying about the quality of the pictures is that if it had been one of the items in the pink box we couldnt see it.

None of these boards are the one retired caps asked for see above.

Re: Dell WFP 2007 No image

Where is the fuse?

Re: Dell WFP 2007 No image

I have uploaded more images at the top of this post, from the other side of the cards, please let me know if you need something specific.

Thanks man!

We need a picture of your panel board. Follow this cable in red and take a picture of that board. It might be behind a metal shield. As I mentioned, it will a long board at the top of the lcd running the entire length of the monitor.

On this panel board might be a SMD fuse which might be marked F1. You will need a multimeter to see if it is good or bad. With power off and lcd unplugged, a good fuse should measure less than 1.0 ohms.

If you don't have a multimeter and don't ever plan to repair any more electronics in the future, then borrow one from a friend. If you want to buy one, I don't know your local market, so you probably want to get something off ebay that provides free shipping? This usually implies buying something from Chinese vendor as they seem to ship worldwide. What is your budget in USA dollars?

If you have a local electronics store that sells multimeters and they have a website, post the URL and I can take a look.

Re: Dell WFP 2007 No image

Retiredcaps is brilliant on the multimeter front. I am sure he can point you in the right direction.

Re: Dell WFP 2007 No image

Re: Dell WFP 2007 No image

@ Selldoor - I thought that when I wrote the post.

@noisepc - We have found out that your screen is lighting up which means that we need to do some further checks. We can talk you through the next stage but you are going to need to get a multimeter.

Thanks for the pics of the bottom of your boards your are going to need to unscrew them and take a similar picture of the top of them as clear and as close as you can. Remember that we are having to look very closely to see what's going on and that can be impossible with a poor picture.

Re: Dell WFP 2007 No image

I have added 2 more images, please let me know if you need more of them.

[selldoor]

Re: Dell WFP 2007 No image

One has a tab and 3 pins and the other has a tab and 2 pins. Please can you tell us the measurements off each pin
@Jasgriff - I think he's going to need some guidance

"I have no idea how to use a multimeter , but I can buy one and learn how to use it if it´s not difficult."

@noisepc - Having sorted the screensaver it is NOT" 2 seconds to black"

Re: Dell WFP 2007 No image

This is a picture of my monitor connected to the PC, without image but with the backlight on.

[retiredcaps]

Re: Dell WFP 2007 No image

Update: The monitor stays with green light on, and the backlight started. It has been there for about 15 minutes, no image.

A picture of the problem would help.

We also need a picture of the panel board. It is the long board that runs the entire length of the lcd at the top.

Re: Dell WFP 2007 No image

Ok,

your picture shows 2 voltage regulators on the bottom left of your picture above.

One has a tab and 3 pins and the other has a tab and 2 pins. Please can you tell us the measurements off each pin and can you tell us what it written on the top of each one.
